Introduction: Regional anaesthesia (spinal anaesthesia) is widely used as a safe anaesthetic technique for both elective and emergency operations. Shivering is known to be a frequent complication, reported in 40 to 70% of patients undergoing surgery under regional anaesthesia. Various methods are available for the control of shivering during anaesthesia. Here we have compared Tramadol, a synthetic opioid with Pethidine, the gold standard drug for the treatment of shivering, in the quest for more safe and efficacious drug.
Materials and Methods: Forty patients of ASA 1 and 2 status posted for elective surgical procedures under neuraxial block were selected. Group P (n=20) received Pethidine 0.5mg/kg IV and group T (n=20) received tramadol 1.0 mg/kg IV.
Results: Both the drugs were found to be effective in reducing shivering. Nineteen patients in the Group T had control of shivering at end of 5 minutes but there were no patients who had control of shivering Group P (p < 0.0001) which is statistically significant.
Conclusion: Tramadol reduced the occurrence of postanesthetic shivering more significantly than pethidine.
